my trouble was usual: just formatted a SD card (Qumo 16 Gb class 10) in my Nikon. Then I came to my friend with r-studio 5.2 installed, we made an image, scanned it and tried to recover photos... The card was full for about a half, containing some videos in .mov & about 1000 pictures in .jpg. The recovery result was unsatisfying: only 10 percent of files (mainly from the start of the card) were readable, and could be opened in common viewers. Then we traveled to frind's company, where used R-studio 7 on the same card... and received NO readable files, while their quantity & sizes match our first try.

Then we run this FREE & opensource tool on that card - and we got all videos & photos fully readable! So why it can be so? Why R-Studio with price over $100 can't do the work, but Photorec does? Maybe your programmers try to find some useful stuff in that sourcecode - than why not to buy some things to improve your commercial product making it more powerful?
